Application filed August 2, 1915. Serial No. 43,145.

To all whom it may concern:

Be it known that I, FRANK O. WooDLAND,

a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Wiper Mechanismfor Labeling-Machines, of which the following is a specification. A

My present invention relates to an improvement in the construction of wiper" cient means for lifting or depressing the wiper or wipers in relation to the plane of the carrier movement, and while acting upon the label, in addition to means for effecting a variable action of the wiper or wipers for lapping or passing the labels around the circumference of the bottle.

A further object is to provide a label wiping means adapted to have a horizontal forward and backward movement in the direction of the path in which the bottle or labeled article is moved, a laterally variable movement in relation thereto, and a vertically variable movement in relation to the plane of the carrier; said movement being independently controlled, but simultaneously effectable upon the label while wiping it upon an advancing bottle, as more fully hereinafter explained.

These objects I attain by a wiper mochanism organized for operation substantially as set forth and illustrated'in 'theaccompanying drawings, wherein Figure 1 is an elevation view of such parts of a label aflixing mechanism asembody my invention, Fig.

2 is a plan view of the same and Fig. 3 is. a vertical section transverse to' the. main carrier arm, at a position adjacent to the inclined track member, and looking toward 0 the outer end of the carrier arm.

A labeling machine representative of the class to which my present invention is adapted and on which it may be employed 1n practice, is illustrated and described in my prior Letters Patent No. 1,113,854, to which reference can be had for a fuller understanding of the general features and operation of parts of the labeling mechanism other vthan those herein shown; since, while necessary to a full operating labeling mechanism, they are not essentially embraced as of my present invention.

. .In referring to the drawings, numeral 10 indicates the main wiper-carrier element or arm which is mounted by a bearing 11 upon the central hub or axis member 12 of a rotating bottle-carrier, to move forward and backward withhorizontally oscillative action, as from line Ato line B, above the car rier or table upon which the bottles or articles to be labeledare" supported and advanced along a path indicated by the dotted line P, as heretofore practised. The arm 10 can be operated by any suitable actuating means which may be connected thereto at 13, or in other efficient manner.

I 15 and 16 indicate laterally swinging wiper-holding members or levers having theirhubs 5 and 6 respectively supported upon upright pivots or fulcrum pins 2 and 3 carried by the arm 10. Said wiper-holding levers project at the front and rear of the arm and are respectively provided at their rear ends with rolls 7 and 8, that engage within suitably shaped cams, grooves or guides 17 and 18 formed in or upon an overlying stationary cam-plate 19 that is supported in connection with the machine frame F. The parts of said wiper-holding levers forward of the carrier arm are curved or turned downward, and adapted for holding the flexible wiper pads 25 and 26 in proper alinement with the labels L, that are presented to the advancing bottle D by means and in the manner set forth in my prior Letters Patent.

In accordance with my present invention the laterally swinging wiper-holding member 15 is arranged to have a bodily up and down movement, or a vertical action in addition to itslateral action. This is attained preferably by arranging its hub-5 to slide on the fulcrum pin 2; the latter projecting upward from the main carrier arm to a sufficient extent to afford the amount of vertical shift that may in any instance be desired;

the roll 7 also being of sufficient length to carried thereby.

A push spring 24: is arranged between the bar 20 and carrier-arm 10, and retained in proper relation by suitable centering bosses. Said spring is tensioned to normally elevate the parts. The bar 20 is best furnished with a bearing boss 23 upon its upper side. A depending curved rib or cam-track 27 is provided upon the under side of the camplate 19, for acting against the boss 23 or top of the lift-bar 20 as the carrier element 10 swings thereunder forward and back; said cam-track 27 having an inclined or shaped contact surface that effects a vertical movement of the swinging bar 20, wiper holder 15 and devices connected therewith; so that while the bottle moves forward in a horizontal plane the wiper, while wiping,

tion 1O of the wi er-carrier element 10; the

upper part of sai rocking head being pivotally connected with the lever 16 by a link 31 so as to rock the head and wiper when lateral swing movement is imparted to the lever by its roll 8 moving along the groove in the cam-plate.

' In the present drawings only one of the pair of wipers is shown as having means for its vertical shifting action, but like construction may be employed for both or either of the wipers, if so desired.

In the operation, the forwardly moving bottle D, after the gummed label has been delivered thereto, enters between the wipers 25 and 26 .at about the line A, and passes beyond the reach of the wipers when the latter have been carried'to about the line B by the horizontal swing of the wiper-carrier arm 10. During such movement the action of the cam-track 27 upon the lift-bar 20,

causes a depression of the wiper-holding member 15, thereby moving the wiper 25 lengthwise of the bottle, as from the position shown in full lines to the position indicated by dotted line 25, more or less, to ac cord with the spiral set or incline of the wing of the label; while at the same time the wipers swing inward laterally, for wiping the end of the label across the rear side of the bottle as desired, without interference of the vertical action of the wiper.

What I claim and desire to secure by Letters Patent is 1. A label wiper mechanism including a main wiper-carrier element arranged to have forward and backward movement in a direction approximately parallel with the path of the moving bottles or articles to which the labels are affixed, a wiper-holding member mounted upon said wiper-carrier and adapted to have lateral movement in respect to the direction of the main wiper- -carrier movement, and vertical movement approximately perpendicular to the plane of the main carrier movement, a wiper secured to said wiper-holding member, means for operating said main wiper-carrier, means for controlling the lateral action of said wiper-holding member, and means for independently imparting the vertical movement to said wiper-holding member and wiper whilethe wiper is in contact with the label.

2. In alabel-affixing mechanism of the class described, a wiperholding member arranged to have a lateral movement and a vertical movement, and means for independently controlling said movements simultaneously with the wiping action; in combination with a wiper-carrying element upon which said wiper holding member is supported, having forward and backward movement as successive bottles or the like move in conjunction with said wiper mechanism.

3. In a mechanism for the purpose described,the combination, of a horizontally moving main wiper-carrier element that travels forward and backward along the path of the advancing bottles, a laterally swinging vertically shiftable lever pivotally fulcrumed upon said carrier and having a wiper connected with one of its ends, and a cam-engaging roll at its other end; means for shifting said wipenholding lever on its fulcrum pin, comprising a spring for lifting the same, a stationary cam-plate having a slot engaging said roll for controlling the lateral relation of the wiper, and a rib fixed on said cam-plate and having an inclined or cam surface that acts in opposite direction to said spring for effecting and controlling the vertical movement of the wiper means as the main wiper-carrier element passes beneath said cam-plate.

4:. In a label wiping mechanism, the combination of a main wiper-carrier, a wiper, a wiper-holding member slidably mounted upon an upright pin projecting from said main carrier, a shifting bar fulcrumed on the main carrier and having its swinging end operatively connected with said wiperholding member, a spring acting against said bar to efiect movement thereof in one direction, and an inclined track or cam that contacts with said bar in opposition to said spring for effecting movement of said wipersupporting member for varying the position of the wiping contact in lengthwise relation to the bottle while wiping the label thereon.

5. In a wiper mechanism for rotary-carrier bottle-labeling machines, the combination, of a horizontally oscillating supportmg-arm having its axial bearing upon or coincident with the axial member of the rotary bottle carrier, laterally swinging wipershifting members pivotally mounted upon said supporting arm and provided with camengaging means, one of said members movable up and down on its pivot pin, a vertically swinging lift-bar fulcrumed upon the supporting-arm and engaging within an opening in said wiper-shifting member, a push spring disposed between the lift-bar and supporting arm, an overlying cam-plate having cam slots and a cam member that contacts with said lift-bar for controlling vertical variation of the wiper devices simultaneously with the lateral movement of the wiper-shifting members during the wiping-on action. 7
